A tube-like garment made of elastic material (e.g., circular knit nylon and Spandex yarns) that exerts a pressure upon the limb upon which it is fitted (typically a leg, but some types may be used on an arm), primarily to improve venous return to treat/prevent one or more disorders of circulation [e.g., oedema, deep vein thrombosis (DVT), varicosis]. It might be referred to as a compression stocking or flight sock and may be intended to apply a graduated pressure across a limb, however it is not intended to support an injured joint. It is normally available [non-prescription] over-the-counter (OTC) for home-use and/or for hospitalized or institutionalized patients. This is a reusable device.
